What is the profit margin of purchasing?

The generation gap, in addition to the gap caused by the factors of the times in the traditional sense, also has the contradiction caused by the differences of space culture. The latter, for me, is fatal. Like a thorn hidden in clothes, it comes out from time to time and sticks it.

This generation gap is mainly reflected in the principle of dealing with people. I am an obedient boy, adhering to the fine traditions of the Chinese nation: kindness, tolerance and respect for teachers. As a result, many friends feel wronged for me about some things at work and feel that I have been bullied. Although I know that they may think that cowardice in my character will make me ignore myself and go crazy to catch the job that my teacher/colleague throws at me. It's a similar situation this time. This semester, I worked as a laboratory assistant for a teacher in a class at school. This teacher is very serious and responsible, and gives students homework every week. My duty, according to the school recruitment information, is to help students operate the software during class hours every week. My salary is also paid according to the time spent in the laboratory, unlike the salary of another course, which includes extra time for preparing lessons and answering questions in addition to teaching time. However, after taking over this course this semester, a series of activities, such as weekly homework, lesson preparation, laboratory maintenance, user guide update, etc., fell on me, and countless emails from followers were distributed to my mailbox during the day, evening and even early morning. I do it for free, staying up late and working overtime. During the day, I am busy writing my graduation thesis, writing papers, attending classes and having meetings, and then correcting students' homework at night. 90 students per week, with an average of 1-2 homework. We should not only judge right or wrong, but also give concrete feedback. In this way, the time for correcting homework alone accounts for about 1-2 hours per week. Because I don't want to delay my scientific research progress or my part-time job (I have been doing part-time job because I want to reduce the burden on my family by studying at my own expense), this part of the time is after I finish my main work in the evening. Originally in poor health, I stayed up for a month and fell ill completely. I have a fever, a cough, a headache, and I am still correcting my homework in front of the computer in bed.

My symptoms are a little better today. I made a video with my parents and began to vomit. I got a very negative evaluation. They think that as a student, I should be grateful to the teacher for giving me the opportunity, not complaining. Although I explained that I didn't complain to them until after this time, it seems that they still think I am not patient enough. Further, I don't respect the teacher and don't cherish the opportunity to handle chores for me. Laugh. During these years in the UK, I have always felt that being a teacher's ta is a good experience and I can learn a lot. But only this once. This exception also completely erased everything my parents thought was "right". While arguing with my mother with a sore throat, I heard my father say loudly across the screen, "Don't take this course from next week!" " . My mother echoed, "I don't want to talk to you when I see your father, and the father who loves you the most in the world doesn't want to take you." Then I hung up the video.
